Also for your rough idle, I suggest sending your injectors out to be cleaned if you haven't already. My motor sat for many many years before it was fired. Those injectors get gummed up. Mine lopped like a Harley before I cleaned the injectors. After it ran so much smoother.

Thanks - that's what we're looking into. My other brother, Steve, did most of the engine work and I think he got new injectors, but I'm not 100%. We'll check them. Probably get some sea foam and run it through too. We did burn up the 1st fuel pump from crap in the tank that we missed, so we'll probably check filters again too.
